6.) Use cross products to determine which ratio forms a proportion with
9/4
To determine which ratio forms a proportion with 9/4, we can set up and solve the following equation:
x/1 = 9/4
We can cross multiply:
4x = 9(1)
4x = 9
To solve for x, we divide both sides of the equation by 4:
x = 9/4
Therefore, the ratio 9/4 forms a proportion with itself.
